Recover the Deleted files in Fedora 11

What is Photorec?

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its ‘Photo Recovery’ name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media’s filesystem has been severely damaged or re-formatted.

For This HowTo Recover Deleted Files?

Lets say I had a file download_arrow.png in /home/aryan/Desktop which I have removed accidentally. Login as root and create a directory recover which will be used to store all the recovered files.

Install testdisk/PhotoRec

Photorec comes as a part of testdisk package in Fedora (I hope its same for other distributions as well). Use yum to install testdisk.

[root@fedora-tips ~]$ yum install testdisk

Launch Photorec

Once you are done with installation. Open a terminal and launch photorec (as root).

[root@fedora-tips recover]$ photorec

Select Hard Disk

If you have more than one hard disk in your system, select the one from which you have deleted the file(s).

Select Partition Type

If your hard disk has Linux partitions, then select [Intel].

Select Filetype Option

Move to [File Opt] and press enter. Here you can disable all file types by pressing ’s’ . Use space to toggle the check button. Now since we removed a png file, we are going to check only png file type.

Select Options

Photorec also has a list of different options. Under normal circumstances you don’t need to modify them

Select Partition

Move the selector to the partition from which you have removed the file. Then press enter on search.

Select Filesystem Type

If you are using Linux, its going to be ext2/ext3/ext4. So the default selection is file.

Select Space for Analysis

Select free if you didn’t write to that partition after removing the particular file otherwise select whole.

Select a Directory to Recover Files

Now select the path where the recovered files will be stored. Then press ‘Y’.

Recovery Progress

Photorec will show how many files it has recovered.

All recovered file will be stored in the directory selected above. Open them in a file browser and you’ll get the removed file there. I hope this howto will help you recovering files you accidentally delete

Install an IBM Web Application Server - Community Edition(WAS-CE) in Fedora 11

Installation Steps:

STEP 1:Download the installation bundle of WAS-CE with ibm-sdk150 java from
http://en.wikipedia.org/wiki/Ia32

STEP 2:Installation of application server :

• Extract the files from wasce_ibm150sdk_setup-version-platform.tar.bz2 into an empty directory using a utility that supports the tar/bzip2 format using
  

[root@localhost Download]#tar -jxf wasce_ibm150sdk_setup-version-platform.tar.bz2
or
[root@localhost Download]#bzip2 -d wasce_ibm150sdk_setup-version-platform.tar.bz2

• Install the dependent packages for wasce

[root@localhost ~]#yum install libXp libXp-devel compat-libstdc++-33

• Install the IBM SDK Java(TM) 2 Technology Edition by invoking rpm package manager on .rpm file from the directory created above

[root@localhost ibm_was_ce]#rpm -Uvh ibm-java2-i386-sdk-5.0-10.0.i386.rpm

• Make wasce_setup-version-unix.bin executable

[root@localhost ibm_was_ce]#chmod 755 wasce_setup-2.1.1.3-unix.bin

• Install the application server wasce_setup-version-unix.bin from the directory created above and follow the instructions provided by the install wizard

[root@localhost ibm_was_ce]#./wasce_setup-2.1.1.3-unix.bin

• After a successful installation, the wasce_ibm150sdk_setup-version-platform.tar.bz2 file and the directory created above are only needed if you want to perform another installation. The installed application server does not require them. You may delete or archive them to suit your conventions.

STEP 3:

• Starting the server

[root@localhost ~]#cd /opt/IBM/WebSphere/AppServerCommunityEdition/bin
[root@localhost bin]#./startup.sh
Using GERONIMO_HOME: /opt/IBM/WebSphere/AppServerCommunityEdition
Using GERONIMO_TMPDIR: var/temp
Using JRE_HOME: /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/jre
Using GERONIMO_OUT: /opt/IBM/WebSphere/AppServerCommunityEdition/var/log/server.out

Geronimo started in background. PID: 6899

This indicates that your server is started successfully.

• The server will be started in the background and the server's output will be written to /var/log/server.out. When initialization is complete, this file contains a list of ports on which the server is listening, application modules started, active web application URLs, and should end with the server started message.

Step 4:Verifying the server

After your server has successfully started, access these pages to verify the installation:

• Navigate your browser to the welcome page at http://localhost:8080/.
• Navigate your browser to the administrative console at http://localhost:8080/console and log on using:
  • Default username = system
  • Default password = manager

Step 5:Stopping the server

[root@localhost bin]#./shutdown.sh
Using GERONIMO_HOME: /opt/IBM/WebSphere/AppServerCommunityEdition
Using GERONIMO_TMPDIR: var/temp
Using JRE_HOME: /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/jre
Username: system
Password: *******
Locating server on localhost:1099... Server found.
Server shutdown started
Server shutdown completed

Installing a package from the source in UBUNTU 9.04

Installing a package from source

• Make sure you have all the necessary development tools (i.e. libraries, compilers, headers):

aryan@aryan-laptop~$sudo apt-get install build-essential
aryan@aryan-laptop~$sudo apt-get install linux-headers-`uname -r`

Note: "uname -r" lists the current kernel you are using

• Extract the archive that contains the source files:

aryan@aryan-laptop~$tar xvf sourcefilesarchive.tar.gz

• Build the package using the package's script (in this case the configure script), compile the package (make), and install the compiled package into your system (make install):

aryan@aryan-laptop~$cd /path/to/extracted/sourcefiles
aryan@aryan-laptop~$./configure
aryan@aryan-laptop~$sudo make
aryan@aryan-laptop~$sudo make install

Note: typing ./ before a filename in the current folder allows the Linux shell to try and execute the file as an application even if it is not in the path (the set of folders which it searches when you type a command name). If you get a "permission denied" error, the file is not marked as being executable. To fix this:

aryan@aryan-laptop~$sudo chmod +x filename

Example: In the above instructions, configure is the shell script to build the package from source. To be sure the configure script is executable:

aryan@aryan-laptop~$sudo chmod +x configure

Handling .tar.gz and .tar.bz2 files in ubuntu 9.04

Handling (Tar/GZip) and (Tar/Bzip2) archives

(Tar/GZip) archives end in ".tar.gz" and (Tar/Bzip2) archives end in ".tar.bz2". Bzip2 is the newer, more efficient compression method. These files can generally be automatically extracted by merely clicking on them from your file manager (Nautilus), since file associations with the appropriate archival utilities are set by default in Ubuntu. These instructions are for those who wish to use the command line Terminal.

• To extract:

aryan@aryan-laptop:~$tar xvf packagename.tar.gz

Note: tar is an application which can extract files from an archive, decompressing if necessary.

-x means extract.

-v means verbose (list what it is extracting).

-f specifies the file to use.

• Decompressing ".gz" files

aryan@aryan-laptop:~$gunzip file.gz

• Decompressing ".bz2" files

aryan@aryan-laptop:~$bunzip2 file.bz2

Note: You can also decompress a package first by using the command gunzip (for .gz) or bunzip2 (for .bz2), leaving the .tar file. You would then use tar to extract it.

• To create a .gz archive:

aryan@aryan-laptop:~$tar cvfz packagename.tar.gz folder

• To create a .bz2 archive:

aryan@aryan-laptop:~$tar cvfj packagename.tar.bz2 folder

apt and package basics in ubuntu 9.04

These instructions are for installing packages from the command-line Terminal. Terminal can be started:

Applications -> Accessories -> Terminal

• Install packages:

aryan@aryan-laptop:~$sudo apt-get install packagename

Example:

aryan@aryan-laptop:~$sudo apt-get install vlc

• Remove packages:

aryan@aryan-laptop:~$sudo apt-get remove packagename

• To remove all dependencies:

aryan@aryan-laptop:~$sudo apt-get autoremove
Example:

aryan@aryan-laptop:~$sudo apt-get remove mpd sbackup

• Search for packages:

aryan@aryan-laptop:~$apt-cache search 
Examples:

aryan@aryan-laptop:~$apt-cache search Music MP3
aryan@aryan-laptop:~$apt-cache search "Text Editor"

• Update the apt package database after adding/removing repositories:

aryan@aryan-laptop:~$sudo apt-get update

• Upgrade packages:

aryan@aryan-laptop:~$sudo apt-get upgrade

• Upgrade the entire distribution (e.g. from Intrepid to Jaunty):

aryan@aryan-laptop:~$sudo apt-get dist-upgrade
